Abstract excerpt

In Japan, the increasing incidence of β-lactum-resistant Haemophilus influenzae infections is of growing concern. We retrospectively studied whether the prevalence of β-lactamase-negative ampicillin-resistant strains of H. influenzae was influenced by chronic lung diseases. H. influenzae isolates, obtained from patients who were diagnosed with acute or chronic bronchitis, or acute exacerbation of chronic...
